High-capacity BESS for energy-demanding sites

The PowerBase XL is a high-capacity energy storage system. Designed for quick deployment on a steel skid with container-format footprint. It is easy to transport to new locations if needed.

Fully integrated, pre-wired and factory configured system that reduces the installation time significantly.
The BESS that pays for itself by earning from electricity markets and saving cost through peak shaving and power boost.
Built for future-proof performance
Designed and manufactured in Europe. Combining robust engineering with high-quality components to deliver modular, scalable and reliable energy storage for critical applications and demanding environments.
Secure, connected, and compliant
Our 48V systems are built for always-on operation. Encrypted communications, secure remote access, and full GDPR compliance, enabling uninterrupted connectivity, real-time insight, and maximum ROI through value stacking.
Resilient by design, reliable in use
Pixii BESS feature built-in redundancy, active monitoring, and automated recovery protocols. This ensures secure operation even under failure or cyber threat, ideal for mission-critical energy storage needs.
Pre-wired, pre-configured
The base is designed for easy deployment. Cabinets can be shipped with batteries installed and come pre-wired, with a separate AC distribution cabinet to simplify installation and reduce on-site work.
